The .miniature calendar, according'to Vthis in- 1 vention,xis. associated with acap 10 having a side window llyandanY openingf 12 extended infrom one end.,y A body is insertedlinto the open end of the cap-'and haslaiweb support 13 located immediatelybehind the Window opening 11. A calendar Web-1dV is :extended over the web support 13 and is wound upon rollers 15 andL 16 mounted within the rbody. A means is provided for Winding the web fromV one .to lthe vother of .the rollers -to exposediiferent portions. of the web through the vvWindow,v and this means includes aknob 17 for its operation`,fsaid knob :also covering the open'end of the cap. 10i. :The upper Aend ofthe cap '10 has a slightly reduced. portion 10ev extending 'slightly into -the knob/for avoiding a space between these parts. l l

The window 1l is closed'by a piece of transparent material 18. y'lhefvvindow l1 is surrounded by vrecessed sides .11.i`nto which the Yedges of the-transparent material-18 engage; :The recess y 11 serves to removablyy holdithe transparent material. This.arrangementallowsiremoval of the transparent material sothat 'access may. be .had to the interior of thecap 10 furthe purpose of removing the calendar or adjusting the calendar orother'similar reasons. The cap 10 isshown provided .with 'a regular-clip .19. The bottom sidegjof `thelcap isopens'o as tofbe engag'eable upona fountain `pen according to conventional practice... The body,y which is lengaged into `the opening l2, comprises several horizontal discs,V illustrated as three in all, indicated by reference numerals 20 v 21 #and 22 arranged superimposed with thedisc 20 at thebottom and a disc 22 atthe Y top. Av continuation 23 of smaller width con- ;nects one vside of the disck 22 :with the disc 21. 'Ihe webVV support 13 .connects the discs 20 and :21.

VVa

- engagedrinto openings 34 in the top disc 21.

Other supports, strips 24, extend between the discs 20, 21 and 22 and hold these discs as a unit. The rollers 15 and 16 are fixed upon vertical shafts 25 rotatively engaged through the discs 20,

21 and 22`and arranged with similar crank portions 26 located in the space between the discs 21 and v22. A central shaft 27 is also rotatively mounted through the discs 20, 21V and 22 and also has a crank portion 26 similar to the crank portions 26 previously mentioned andy also located in the space between the discs 21 and 22.

A bar 2S connects all of the cranks 26 together to cause them to rotate in unison. The cranks engage through openings in the bar 28 so asA to be turnable therein. The knob 17 is mounted upon the upper end of the shaft 2 '7;which.is.ex--v tended above the disc 22. yThe shafts 25 terminate at the disc 21. U Y

The upper end of the shaft 27 is formed with a square head 29 which slidably engages in a similar .shapedA opening 30 arranged upon-the knob 1'7. Springs `31 andl 31' are' interposed in the opening 30 and act between the base and top ofthe opening 30 and theghead 29 so as to normally hold the knob in a neutral intermediate position. A plug32 closes the. bottom. ofthe opening'SO, andthe upper end of the shaft 27 slidably passes through this plug. Several pegs 33 project from the bottomof the knob 17 and have rounded bottom ends normally` slightly The normal position of the pegs is illustrated in Fig; 11. Thearrangement .f is such-that. when the knob 17 is turned the pegs 33 can ride` out 'of .the apertures 34 whichare arranged close together and in a circle as illustrated in Fig. 3 and so hold the knob 17 in various adjusted positions. The

.spring 3l serves to resiliently urge the knob.17

downwards so as to'cause the, engagement ofthe pegs 33 into the top portions of the. openings 34. If desired the knob17;may be depressed against the action ofthe spring 31 soas .to extend the pegs 33' sufficiently deep into the openings 34 Vto connect the'knob and theV discforl turning the body of the calendar. 'f

A finger 35 projects from the periphery of the bottom disc 20 and engages in a longitudinal slot 36 former upon the innerwall of the cap and extending from the open :end downwardsto a` window opening 11 of a size to completely expose l Y one month upon the Web. l.

Theroperation of the device consists-in turning the knob 17 in one direction or the other to similarly move the webto expose different portions.

As the knob 17 is turned the shaft 27 willturnY correspondingly and the` bar` 28 Willtransmit this motion to the cranks 26 to rotatetherollers 15 and 16 to unwind .the .web from one of the rollers to the other. The calendar'web may be changed by removing the .transparent `material 18 and reaching the .web through the openingv 12. The calendar Web may alsobe-changed by removing the entire body. Todo this, it is 'necessary that the knob 17 be first depressed to engage the pegs 33 into the openings 34. Then the body should be slightly turned so as to disengage the finger 35 from the portion 37 of the groove in the inner wall of the cap. The slight turn presses the finger 35 with the groove 36 and then the spring 38 slightly ejects the body. The body may next be lifted out completely from the cap. The knob 17 maythen be turned in one direction until the web is vcompletely wound uponY one roller only Y and the end disengaged from the coreof the other roller.

In Figs. 9 to 11 a modification of the invention has been disclosed which distinguishes from the previous-form-merely in the manner in which rotations are transmitted to the rollers. More particularly, a central gear is fixed upon the central shaft-.'27 andY meshes with gears 46 upon `the shafts `25 .of the rollers.

In other respects this form is similar to the previous form, the same parts may berecognized by the same reference numerals. When the knob 17 is turned the shaft 27 will also be moved and the gearv 45 will simultaneously turn the gears 46 in onedirection or the other as desired.Y y

i In Fig. 12 another variation of the invention has been disclosed in which a cap 1 -1G is engaged upon a pencil 48., This Acap isshown with a reduced bottom portion 49 to engage upon the end of `the pencilwhich is of smaller diameter compared with the main portion of the cap ,10. In otherrespects the form of the invention is identical to that previously described and similar parts may.be recognizedby 4corresponding reference numerals. 1 Y .i .While Lhave shownV and .described the preferred embodimentpof my invention,. itis to be understoodthat vI do not-limit myself tothe precise construction herein disclosed and'itheright is reserved to all changes and modifications coming Within the' sc ope ofthe invention as defined in the appended claims. y
